About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LGS2F15856 or S2F15856. Listed at 2 retailers as of October 30, 2026, with prices from $1,450 to $2,498, a $1,047 spread on the same certified stone. Yorxs lists it at $2,498. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
